Karyotype stability, which is essential when using wheat (Triticum aestivum L.) doubled haploids in a breeding program, was evaluated in 14 anther-derived doubled-haploid lines after at least three generations of selfing, by crossing them as females with the parent cultivar 'Centurk' and doing cytological studies on the progenies. There were no deviations from the hexaploid chromosome number (2n = 42) in root tips. Meiotic chromosome pairing was as stable as that in the control ('Centurk' × 'Centurk') in most progenies. Chromosomal structural changes and (or) behavioral deviations were detected at the metaphase I, anaphase I, telophase I, and quartet stages of meiosis in a minor proportion of the cells. The frequencies of multivalents, lagging bivalents and univalents, bridges, and micronuclei were higher in some progenies than in the control. Chromosomal fragments were infrequent. The ranges in percentages of normal cells were 72.4–90.0 at anaphase I, 76.4–92.6 at telophase I, and 82.6–93.2 at quartet stages in the doubled-haploid progenies, compared with 95–100, 92–100, and 94–96, respectively, in the control. On the basis of these results, the doubled-haploid lines should produce enough normal gametes to provide adequate seed supplies when they are used as parents in wheat cultivar and population improvement.Key words: Triticum aestivum, chromosome pairing, chromosome aberrations, gametoclonal variation.

We investigated the anther culture (AC) efficiency of thirteen F<sub>4</sub> combinations of winter wheat (Triticum aestivum L.). The genotype dependency was assessed during the induction of the androgenic entities, i.e. embryo-like structures (ELS), regenerated-, green-, albino-, and transplanted plantlets. The number of green plantlets per 100 anthers (GP/100A) varied from 0.36 to 24.74 GP/100A with a mean of 8.31 GP/100A. Albino plantlets (AP) occurred in each combination, ranging from 0.20 to 22.80 AP/100A with an average value of 5.59 AP/100A. Between 25–87.76 doubled haploid (DH) plants per 100 acclimatised plantlets (DH/100ADP), depending on the combination, with a mean of 59.74% were recovered. We have found the highest DH production in the combinations Béres/Midas, Kalász/Tacitus, Béres/Pamier, and Premio/5009. This improves remarkably the choice of basic genetic material in subsequent crossing programmes. These observations emphasise the usability and efficiency of in vitro AC in producing a large number of DH lines for breeding and the applied researches of winter wheat. Although albinism was found in each combination, it was mitigated by the in vitro AC application.

Cluster Distance

Genetic divergence of 17 doubled haploid lines and 3 check varieties of spring wheat were assessed through Mahalanobis’ D2-statistics. The genotypes were grouped into six clusters. The clusters I and III contained the highest number of lines (5). The cluster V contained single genotype. The maximum inter-cluster distance was noticed between the clusters I and V and minimum between III and VI. The highest intra-cluster distance was observed in the cluster IV and lowest in the cluster V.DOI: http://dx.doi.org/10.3329/bjpbg.v20i2.17034

Cultivar Description

Karat is a winter wheat (Triticum aestivum L. em. Thell.) with bread making quality, high grain yield, and adequate straw strength. It is moderately susceptible to powdery mildew (caused by Erysiphe graminis D.C. ex. Merat f. sp. tritici Marchal) and septoria leaf and glume blotch (caused by Septoria nodorum Berk.) and is suited for production in areas of Eastern Canada where winter survival is not a problem.
